[PVE-User] (Very) basic question regarding PVE Ceph integration

Hi,

I understand that with the new PVE release PVE hosts (hypervisors) can 
be used as Ceph servers.  But it's not clear to me if (or when) that 
makes sense.  Do I really want to have Ceph MDS/OSD on the same hardware 
as my hypervisors?  Doesn't that a) accumulate multiple POFs on the same 
hardware and b) occupy computing resources (CPU, RAM), that I'd rather 
use for my VMs and containers?  Wouldn't I rather want to have a 
separate Ceph cluster?

Or didn't I get the point of the Ceph integration?

Cheers
Frank
